3 Claims. (01. 139-403)- The present invention relates to textile pilefabrics and more particularly to textile struc--' tures adaptable forrug and carpet manufacture.

The principal object of this invention is to provide a novel andimproved pile fabric having a through-to-the-back bind, affording astrong textile structure for the rug and carpet manufacturing art.

In the accompanying drawings forming part of this specification, similarcharacters of reference indicate corresponding parts in all the views.

Fig.. 1 is a diagrammatic warpwise view showing the weave structureeffected in alternate courses of the fabric in accordance with theteachings of this invention.

Fig. 2 is a similar view showing the weave structure made in theintermediate courses of said fabric.

Fig. 3 is a similar view showing the composite weave in adjacent coursesof the fabric.

Fig. 4 is a diagrammatic weftwise view of the said fabric. The coursesare here indicated.

Fig. 5 shows a top view of the pile fabric made pursuant to thisinvention.

In the drawings, in each warp course of the fabric illustrated, thereare warp stuffer, one .pile yarn and a pair of warp yarns to form thebinding chain. The alternate courses are marked A and the coursesintermediate these are indicated as B. In the courses A, the warpstuffer yarns are denoted by the numeral 25, the pile yarn is indicatedby the numeral 26 and the chain yarns are designated respectively In thecourses B, the stufier yarns are indicated by the numeral 35, the pileyarn is 36 and the chain yarns are 31 and 3'! respectively. A web 30 isformed of the stuffer yarns 25, 35, incorporating what shall be calledthe upper wefts indicated by the odd numerals from to ll, to make suchweb. Intermediate each two upper wefts and below the web 30, but abovethe pile yarns 26, 36, there is positioned a weft. These wefts, hereincalled the lower wefts are denoted by the even numbers 2 to I8. Thebinding yarns 21, 21, and 31, 31', form chain engaging the upper sidesof the upper wefts and the undersides of the lower wefts in a manner tobe described. Loops 29, 29', 29", 29" are raised in each pile warp 26 toextend through the web 30 and above its upper surface. Loops 39, 39',39", 39' are likewise raised from the pile warps 36. The position ofsaid pile loops with respect to each other and their relation with. theother components, will be described.

. loops respectively,

vIn the web 3ll,'the stuffer yarns 25 are over alternate upper wefts andunder the other upper wefts, while the stuffer yarns 35 are under thoseupper wefts the yarns 25 are over, and over those upper weftsl't'he-said yarns 25 are under.

Each of the pile loops. ofthe series 29 and 39, have through them .twoadjacent upper wefts and also the lower weft which is intermediate suchpair of upper wefts. .For instance, the pile loop 29 in Fig.

and 1. 1 I

In each pile yarn, two successive loops have through them respectively,successive pairs of upper wefts and one lower weft respectively; thelower wefts thus associated withtwo' successive are in alternaterelation among the lower wefts. The lower weft intermediate such twolower wefts, is above such pile yarn, between saidsucce'ssive loops. Forinstance, the two successive loops 29' and 29" in Fig. 1, have throughthem the wefts 5, 6 and I through one, and 9, l0 and I l through theother, while weft 8 is above the pile yarn 26, between such successivepile loops.

In one direction warpwise, one chain yarn in each of the courses, isunder all lower wefts which are between successive loops in the pileyarn in the course of the chain yarn dealt with, and over all thoseupper wefts first nearest to said lower wefts which are between thesuccessive loops. In the same direction warpwise, the second chain yarnin each course, is under all the lower wefts lying through the loops insaid pile yarn in its course, and over the other upper wefts which arethrough said loops. For instance, in the direction from left to right inFig. '1, the chain yarn 21 is under the lower wefts 4. 8, iii, and overthe upper wefts 5, 9, It. In the same direction, the associated chainyarn 21' is under the lower wefts 2, 6, I0, and over the upper wefts 3,1, II.

The loops in adjacent courses are in staggered overlapping relationbecause the lower wefts which are through the loops in alternatecourses, are those which are between the loops in the remaining courses.For instance, the lower wefts 2, 6, H), which are through the pile loopsof the series 29, are between successive pile loops of the series 39.

In each course A and B, the loops raised from the pile yarn therealong,are preferably between the stuifer warp and the chain yarn in thecourse. The pile yarns ma} all be of one color, or of different colorsas may be desired. .Also, the loops may be cut as is known in the art.

The pertinent advantage of the construction 1, has through it the wefts5, 6

in pile fabrics herein set forth, is that pile yarn goes under the lowerweft, locking same in place and thereby effecting a strung bind, and avery sturdy structure is gained by the included web 38 formedvofitheustufler interwoven with the 5 upper wefti'i.

Having described the structure of my new and improved pile fabrics, Idesire that the following, be protected by Letters Patent, andtherefore, claim:
